I bought tickets on Thursday and arrived to a Friday screening, on time. Even though I had tickets, I was told I couldn't get in (they fully admitted that they oversold the show). There was also a woman with four kids who was in the same situation that they turned away, too.
The manager was not really apologetic. They refunded my money, but I was pretty surprised that they weren't more sympathetic (they were just like, "Yeah, we oversold the show. Here's a refund." I also had to demand the refund—they definitely didn't offer it).
Look on the bright side, anonymous accuser—at least you didn't get bedbugs.
